Chelsea boss Frank Lampard says they'll only sign players who can make the difference.

Speaking on Friday, Lampard insisted he was thinking of the team's best interests, and won't bring in any new players just for the sake of it.

“I think I should be because that's where we're at at the moment," he said when asked if he was prepared to go through the window with no incomings. “If it feels right for us then we'll do it.

“I think the idea of January being a time to buy players, it's difficult for everybody: for players coming in – especially if they're coming from a different league – for the club and for the settlement of the group.

“I think that's why we have to think ultra-carefully.

“I don't want to make some kneejerk reaction to say: 'Here's my first big signing' because we couldn't sign anyone in the summer.

“No, I want to do the right thing for the club. That's why if I do it I'll try to consider all things.

“Hopefully it's the best thing for us. Whether that's more of a short-term option or a long-term option, we'll also have to consider."
